  • Comparative maps, representing chromosomal locations of homologous genes in different species, are useful sources of information for identifying candidate disease genes and genes determining complex traits. They facilitate gene mapping and linkage prediction in other species, and provide information on genome organization and evolution. Here, the current gene mapping and comparative mapping status of the major livestock species are presented. Two techniques were widely used in comparative mapping: FISH (Fluorescence In Situ Hybridization) and PCR-based mapping using somatic cell hybrid (SCH) or radiation hybrid (RH) panels. New techniques, using, for example, ESTs (Expressed Sequence Tags) or CASTS (Comparatively Anchored Sequence Tagged Sites), also have been developed as useful tools for analyzing comparative genome organization in livestock species, further enabling accurate transfer of valuable information from one species to another.

  • Aerosol concentrations at the CC-Lag site in the Teshio Experimental Forest increased from winter to spring and sometimes showed extremely high values associated with Kosa and/or forest-fire events. The range and mean of the mass concentrations of aerosol chemical species were as follows: total particulate mass, 1.2-29, 5.0; elemental carbon, 0.061-2.2, 0.43; organic carbon, 0.059-3.5, 0.79; and sulfate, 0.12-6.2, 1.8 ${\mu}g/m^3$. The total masses of the deposited particles on hybrid larch and on bamboo leaves were approximately 35 and 30 ${\mu}g/cm^2$, respectively. The amounts of soil particles on the leaves were 6 ${\mu}g/cm^2$ for the upper part of hybrid larch, 2 ${\mu}g/cm^2$ for the lower part of hybrid larch, and 1 ${\mu}g/cm^2$ for Sasa bamboo leaves. The amounts of deposited black carbon were 2.3 ${\mu}g/cm^2$ for the upper part of hybrid larch, 0.6 ${\mu}g/cm^2$ for the lower part of hybrid larch, and 0.2 ${\mu}g/cm^2$ for Sasa bamboo leaves. Half of the total deposited particular mass was attached on the hybrid larch; however, most of the total deposited mass was adhered on the Sasa bamboo leaves. Regardless of the species, there tend to be more deposited particles on the leaves in the upper part than in the lower part, with only a few meters height difference. Comparing the composition of the deposited particles to that of the atmospheric aerosols without any size cut, the fractions of water-soluble material sulfate and sea salt in the deposited aerosols were about one tenth and one hundredth lower than that in the aerosols, respectively. On the basis of the measured concentration and the deposited amount on leaves, the deposition velocity of black carbon was estimated to be approximately 0.5 cm/s.

  • 최근의 기업은 주주의 이윤 극대화를 넘어서 사회적 목표의 달성을 요구받으며, 이에 따라 기업의 경제적 목표와 사회적 목표를 동시에 추구하는 것이 중요하게 여겨지고 있다. 이러한 시대적 배경에서 하이브리드 조직에 대한 연구는 이론적·실무적으로 중요성이 증가하고 있다. 특히 하이브리드 조직은 본질적으로 경제적 목적과 사회적 목적을 동시에 추구하는 이중성을 가지고 있기에, 하이브리드 조직을 둘러싼 여러 이해관계자들의 제도적 요구 또한 모순적이다. 이처럼 모순된 제도적 요구에 하이브리드 조직이 대응하는 방식에 대해 여러 선행연구에서 고찰했으나, 대부분 연구가 특정 시점의 대응에 한정되어 있었다. 따라서 하이브리드 조직이 사업을 확장하고 진화하는 과정에 따라 모순된 제도적 요구에 대한 대응전략이 변화하는 모습을 파악하기에는 한계가 있었다. 본 연구는 하이브리드 조직이 모순된 제도적 요구에 대해 선택적 동조화를 취할 것으로 보았으며, 모순된 제도적 요구에 대한 대응이 조직의 성장과정에 따라 변화할 것으로 보았다. 모순된 제도적 요구에 대한 대응방식의 변화를 파악하기 위해 본 연구는 혁신성·기술성에서 좋은 성과를 내면서 고도화된 수준의 비즈니스모델을 운영하고 있는 소셜벤처인 노을과 에누마를 선정해 사례 연구를 수행하였다. 분석 결과 소셜벤처는 모순된 제도적 요구에 대해 선택적 동조화 방식을 취하며, 소셜벤처의 사업이 고도화됨에 따라 선택적 동조화 과정이 변화하는 모습을 보인다. 구체적으로 사업 초기에는 단일 비즈니스모델로 경제적 요구와 사회적 요구를 동시에 대응하는 모습을 보인다. 이후 사업이 고도화되면 두 개 이상의 비즈니스모델을 운영하여서 일부는 경제적 요구에 대응을 하고, 일부는 사회적 요구에 대응하게 된다. 이는 사업 초기 소셜벤처가 제도적 환경에 대해 정당성을 얻고 생존하기 위해 단일 비즈니스모델로 경제적 요구와 사회적 요구를 동시에 대응하되, 사업 성장기에 접어들면 지속가능한 성장을 추구하고 대규모 미션에 도전하기 위하여 경제적 가치를 추구하는 비즈니스모델과 사회적 가치를 추구하는 비즈니스모델을 분리하여 대응하는 것으로 해석된다. 이를 통해 본 연구는 하이브리드 조직이 성장함에 따라서 모순된 제도적 요구에 대응하는 방식이 달라지는 변화 양상을 밝혀내어 하이브리드 조직에 대한 심층적인 이해에 기여하고자 했다.

  • In this paper, a recently proposed parallel hybrid particle-continuum (DSMC-NS) scheme employing 3D unstructured grid for solving steady-state gas flows involving continuum and rarefied regions is described [1]. Substitution of a density-based NS solver to a pressure-based one that greatly enhances the capability of the proposed hybrid scheme and several practical experiences of implementation learned from the development and verifications are highlighted. At the end, we present some simulation results of a realistic RCS nozzle plume, which is considered very challenging using either a continuum or particle solver alone, to demonstrate the capability of the proposed hybrid DSMC-NS method.

  • Many proteins consist of distinctive domains that can act independently or cooperatively to achieve a unique function. As these domains evolve from a naturally existing repertoire of functional domains, this implies that domain organization is an intrinsic element involved in building the complex structure and function of proteins. Thus, identifying functional domains would appear to be critical to the elucidation of questions related to protein evolution, folding, and the engineering of hybrid proteins for tai- lored applications. However, the simple application of "Lego-like assembly" to the engineering of hybrid proteins is an oversimplification, as many hybrid constructs lack structural stability, usually due to unfavorable domain contacts. Thus, directed evolution, along with computational studies, may help to engineer hybrid proteins with improved physico-chemical properties. Accordingly, this paper introduces several approaches to functional hybrid protein engineering that potentially can be used to create modulators of gene transcription and cell signaling, and novel biosensors to analyze biological functions in vivo.

  • 10kW wind turbine has been successfully commissioned at the King Sejong station in April, 2006. The wind turbine installed is a part of the R&D program for developing a solid wind/diesel hybrid power control system for a remote area such as Antarctica. At the same time, the current research aims to develop an anti-icing and de-icing technologies for a small wind turbine rated under 50kW. Since its commissioning, the turbine has generated about 500kWh for 47days without any system faults. Although sufficient data have not been obtained yet, any trouble has not occurred in the wind/diesel hybrid system based on the current analysis. Concerning on the environmental impact by the wind turbine operation, the turbine is installed within the station boundary in order to meet the Madrid protocol. Therefore, wind turbine operation meets the international requirements for preservation of antarctic ecosystem.

  • Everything in the world is becoming connected and interactive due to the Internet. The future of interactive smart environments such as smart cities, smart industries, or smart farms demand high network bandwidth, high network flexibility, and self-organization systems without costly hardware upgrades, and they provide a sustainable, scalable, and replicable smart environment backbone infrastructure. This paper presents a new Hybrid Software-Defined architecture for integrating Internet-of-Things technologies that are essential technologies for smart environments. It combines a software-defined networking infrastructure and a real-time distributed network framework with an advanced optimization to enable self-configuration, self-management, and self-adaption for providing seamless communication and efficiently managing a vast number of smart heterogeneous devices.

  • During the last four years, the pyrosequencing-based 454 platform has rapidly displaced the traditional Sanger sequencing method due to its high throughput and cost effectiveness. Meanwhile, the Sanger sequencing methodology still provides the longest reads, and paired-end sequencing that is based on that chemistry offers an opportunity to ensure accurate assembly results. In this report, we describe an optimized approach for hybrid de novo genome assembly using pyrosequencing data and varying amounts of Sanger-type reads. 454 platform-derived contigs can be used as single non-breakable virtual reads or converted to simpler contigs that consist of editable, overlapping pseudoreads. These modified contigs maintain their integrity at the first jumpstarting assembly stage and are edited by fragmenting and rejoining. Pre-existing assembly software then can be applied for mixed assembly with 454-derived data and Sanger reads. An effective method for identifying genomic differences between reference and sample sequences in whole-genome resequencing procedures also is suggested.

  • This paper proposes the hybrid fuel cell system that can solve disadvantages of existing fuel cell system and ensure high reliability and high stability. The system consists of PEM fuel cell, Ni-MH battery and power management system. In this system, when the power provided from the fuel cell is higher than the load power, the extra energy may be used to charge the Ni-MH battery. When the fuel cell can not provide enough energy to the load, the shortage of energy will be supplied by the Ni-MH battery. Experimental results show that the output voltage is regulated well during load variations. Also, high system efficiency is achieved.
